Ri fuhren@ through perforations 24a in the plunger 24 forward of the ,arms 29, that operate in said plungers and which are adapted to strike against said arms when the carriage 11 is reciprocated rearwardly to stop said plungers. A plurality of the perforations 24a are preferably provided, as seen in F ig. II, in order that the stop-pins may be variably seated in the plungers'. In the top of. each plunger 24 is a recess 24h, (see Figs. III and IX,) that is adapted to receive a spring-pressed retaining-pin 33, slidably positioned in housings 34, set into one of the bearing-boxes 12, through which the plunger 24 operates. These springpressed retaining-pins serve to hold the plungers from accidental displacement while in their rearmost positions inv order that they may be maintained in fixed positions until positively actuated in the manner to be hereinafter explained.

35 designates an eccentric iixed to the power-shaft 6 and surrounded by a band 36, that operates thereon.

37-is a pitman connected to the band 36 and extending forwardly therefrom.

38 designates a cam member that is slotted i transversely to provide cams 39. (See Figs. III, V, and VH.) This cam member, which is in the form of a rod, is mounted in the uprights 3 at the forward end of the machine and is held from rotation by a clamp 40,1ixed to the cam, member and also to the adjacent upright, as seen in Figs. I and H, the method of seeuringthe clamp to said parts being preferably that of set-screws 41 and 42.

43 is a hollow shaft rotatably mounted u on a cam member 38 and loosely seated in t e uprights 3. This hollow. shaft is provided with apertures 44, (seen most clearly in Fig. VIL) that are locatedl in alinement with the cams 39. The Ishaft extends through one of the uprights 3', and'iixed to the extreme end of said shaft is a crank-arm 45, to which the pitman 37 is loosely fitted.

46 is a ratchet-wheel fixed to the hollow shaft 43 adjacent to the crank-arm 45, and 47 is a springressed pawl carried by the crank-arm and) adapted to engage said ratchet-wheel for the urpose of imparting rotation to the hollow s aft when said crankarm is rocked to and fro through the medium of the pitman 37.

43 designates a rotatable jaw-carrying head mounted upon the hollow shaft 43. This head is provided with a plurality of nutreceiving pockets 49, that are adapted to move in a path of travel directly in front of the nut-receiving jaws 31, carried by the reciprocating p'lungers 24.

, 50 represents nut-cracking jaws set into the rotatable head'48 at the rear ends ofthe pockets 49 and provided with central apertures.

5ll represents ejectors having their outer portions slidably positioned in the apertures in the jaws 50 and having their inner ends seated in apertures 44 in the hollow shaft 43. The ejectors are provided with'annular ribs 52, located thereon at the rear of the jaws 50, I

and they are surrounded by retraotingsprings 53, which serve to hold the inner ends `of the ejectors pressed against the cams 39 of /the ixed cam member 38.' 1- These cams are to force the ejector outwardly immediately y after a nut' has been craeked'between said jaws and the pocket containing the nut is rotated downwardly and away from the opposing jaw 31.

54 designates a gage-finger carried by the forward box 12 of the carriage 11 and whichl is adapted to enter into one of the bores 48 located between the nut-receiving pockets 49, each time that the carriage 11 is reciprocated forwardly and the rotatable headv 4S is rotated to bring the nut-receiving pockets into alinement with the plunger-carried'jaws rlhe gage-finger by entering said bore to center the pockets 49 with res ect to the plunger-carried jaws, so that said plhnger-carried jaws may enter the pockets acourately to exert pressure against the nuts previously deposited in the pockets.

The operation of my niiachine is as follows: The power-shaft 6 being put into motion,

'power is communicated therefrom-'through the crank-wheel 8 and pitman 1() to they segment 17 to rotate the rock-shaft 16 and impart reciproeation .to the carriage 11, due to.

the operation oi' the crank-arm 13 in the bedpocket 1. As the segment 17 oscillates it imparts rotation to the rock-shaft 21 through its intermeshing engagement with the pinion 22 thereon and the trip-Wheels 23 are thereby rotated. At these-me time that the parts mentioned are actuated in the mannerpstated rotation is imparted. to the j auw-carrying head 48 through the medium ofthe eccentric 35, carried by the power-shaft, the band 36 operating thereon and the ptman 37 having driving engagement with the shaft 43, that carries the jaw-carrying head 48, through the .medium of the crank-arm 45, pawl 47, and -ratchet-wheel 46.

The nuts to be cracked are introduced into the pockets 49 of thejawcarrying head, and as said head is rotated the pockets-are in turn brought into alinement with the plunger-carried jaws 3l, at which time the ejector in each advanced jaw 5() is in receded position. 'ihe d'iiving members of the carriage and rotatable jaw-mirrying head are so actuated that the carriage will move forwardly to bring the planger-carrieri jaws ige for imparting forward thrust to the plunger toward said'iirstmamed jaw, substantially as set forth. l

v 7. In a nut-cracking machine, the combination of a reciprocatory carriage, a jaw, a plunger arranged to reciprocate on said carriage and. provided with 'a jaw, a springpressed retaining-pin carried by said carriage and arranged in engagement with sai d plun` ger to hold it against reciprocation relatively to the carriage, and means'for imparting for# ward thrust to s'aid plunger toward said firstnamed jaw; said means comprising a dogpivoted to the plunger and a rocking trip member carried by the carriage, substantially as set forth. 4

8. In a nut-cracking machine, the combination of a jaw, a reciprocatory carriage, a reciprocatory plunger mountedin said carriage,a trippable member carried by said plunger, a trip member carried by said carriage ior engagement with said trippable member, means for drivimgr said trip member, a stop seated in said plunger, and a fixed support withwhich said stop engages to hold said plunger and cause separation of said trippable member and said trip member upon reciprocation of said carriage.

9. In a nut-cracking machine, the combination of a rotatableI head, means for rotating said head, a series of jaws carried by said head, a reciprocatory ejector in each of said jaws, reciprocatory means provided with jaws opposing said head, means for reciproeating said jaw-carrying means, and an ejector mounted in each of said last-named jaws and held from reciprocation therewith.

l0. In a nut-cracking machine, the combination of a cam member, a'hollow perforated shaft fitted to said cam member, a rotatable jaw-carryingT head carried by said shaft, means for rotatingq said shaft, jaws carried by said rotatable member, ejectors seated in said aws and extelidingthrough the perforations in said shaft into bearing with said cam member, and means opposing said head between which and the head-carried jaws the nuts are cracked.

1l. In a nutLcracking machine, the combination of a jaw, a reciprocatory carriage, 'a

lun er reci rocall rmounted in said carria e a trippable member connected to said plunger, a trip member carried by said carriage and arranged to be engaged by said trip pable member to impart forward thrust torsaid plunger, a stop seated in said plunger, and means supported independently of said carriage with which said stop engages to hold said plunger lfrom rearward reciprocation and separate said trippable member from said trip member.
